Problems solved by technology

[0003] It is suitable for acrylic topcoats on architectural coatings or metal surfaces. Use heat-insulating coatings to block the contact and conduction of ultraviolet heat and substrates by insulating heat conduction on the surface of the substrate. It can be applied to ordinary building exterior walls and metal storage tanks, Metal containers and other industries, due to technical limitations, there is little domestic development of heat-insulating coatings, which has a relatively good market prospect

Abstract

The invention discloses thermal insulation coating for waterborne acrylic finishing coat. The thermal insulation coating contains the following raw materials in parts by weight: 20-60 parts of acrylicemulsion resin, 10-15 parts of hollow glass microspheres, 10-15 parts of pigment, 10-30 parts of filler, 0.1-2 parts of wetting agent, 0.1-2 parts of antifreezing agent, 0.1-2 parts of thickening agent, 0.1-2 parts of dispersing agent, 0.1-2 parts of neutralizing agent, 0.1-2 parts of antifoaming agent, 0.1-2 parts of leveling agent, 0.1-5 parts of coalescing agent and 10-30 parts of water. The thermal insulation coating for waterborne acrylic finishing coat has smooth appearance, glass microspheres therein, good thermal conductivity isolation, flexibility, weather resistance, water resistance, easy application property, stain resistance, and bonding strength possessed by an outer wall.

Description

technical field [0001] The invention relates to a heat-insulating coating for water-based acrylic topcoat and a preparation method thereof. Background technique [0002] Acrylic topcoat is a one-component quick-drying topcoat composed of thermoplastic acrylic resin, pigments, additives, solvents, etc. The paint has good color retention and construction performance. Provide protection and decoration for outdoor walls, steel structures, mechanical equipment, motors, etc., and can also be used as a topcoat for relief coating systems. [0003] It is suitable for acrylic topcoats on architectural coatings or metal surfaces. Use heat-insulating coatings to block the contact and conduction of ultraviolet heat and substrates by insulating heat conduction on the surface of the substrate. It can be applied to ordinary building exterior walls and metal storage tanks, For metal container and other industries, due to technical limitations, there is little domestic development of heat-i...
